Cherepanov= Frolov
Turris= not enough exposure to know, but I'll use a left coast friends comparison to Lecavallier at that age.
Alzner= Ryan Whitney - should be where Ryan Whitney is now for the Penguins in a couple of years IMO.
Kane= Comrie + probably plays a little more like Briere but I'm not giving him that much credit yet.
Gagner= Ray Whitney
Van Riemsdyk= In between Isbister and Bertuzzi, seriously could be one of those power forwards people spend a decade waiting for a breakout year from. From reports at the 5 Nations I'm more confident he's going to be closer to a Knuble/Bert. Not quite the power of Bert, but probably better upside than Knuble in his hands.
Voracek= M.Satan. (My opinion is changing as he's started to dominate a little more but he has been a very 'now you see me/now you don't' star at times. Wasn't until the last month+ that he stopped being a player that dissappeared for long stretchs only to pop in here and there with a skill clinic.
Couture = B.Morrison/S.Horcoff
Gllies= R.Fata (speed demon with cruddy hands and little idea of what to do with the puck.) It'll be up to him to adapt to a different type of role as a speedy checker in the NHL IMO (unless the experiment of playing d continues).
